VAPOR-BURNER.

Specification of Letters Patent.

Patented June 18, 1912.

Application filed June 26, 1909. Serial No. 504,556.

dent of Chicago, in the county of Cook and State of Illinois, have invented certain 1111- provements in Vapor-Burners, of which the followlng 1s a spec1ficat1on.

My invention relates to vapor-burners, and

more especially to burners of the type dis closed and claimed in my application for Letters Patent, Serial No. 459,205, filed October 23, 1908, which is adapted to burn hydrocarbon oil, and particularly kerosene.

The present invention is a modification of the burner structure disclosed in my beforementioned application for Letters Patent,

the objects being to makethe burner structure compact and slmple in oonstructlon so that it may be readily adapted to ordinary,

lighting purposes for stores, houses etc., the burner tips belng carried by arms slmllar to the ordmary gas fixture or chandelier.

With the objects stated in view, the present invention consists in the novel construc tion and arrangement of parts, and details thereof, as hereinafter described with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the drawings: Figure 1 is a side view of a gas fixture showing an embodiment ofthe invention; and Fig. 2 is a central vertical section thereof.

Referring to the drawings, in whlch the same reference numerals indicate the same or correspondmg parts in both v1'ews,the

numeral 1 designates a globular casing within which is centrally disposed a removable cylinder 2 provided with perforations 13 disposed in rows around its periphery, which cylinder incloses a chamber forming the heating chamber around the vapor generator 3. This vapor generator 3 is constructed substantially as set forth in the beforementioned application, and consists essentially of a tube 3 slightly tapered at its lower end to fit a tapering socket in the cap or plug 5 movably seated in the upper end of a casting 6, said cap or plug having a contracted discharge orifice at its lower end, through which the vapor passes into the air-mixing chamber 39 inclosed by the casting 6, the latter being provided with elongated air-inlet openings 18, through which the air passes from the atmosphere into said.

air-mixing chamber 39, as it is drawn into said chamber by the vapor passing through the orlfice 30 mto sald alr-mlxlng chamber,

the mixture passing downwardly through the pipe or tube 7 forming a part of the conduit for the mixture of air and vapor, and communicating with the conduits 16 leading, in the present instance, in the form of a ring, to the chamber or reservoir 1. The upper end of the vapor generator 3 is likewise slightly tapered and seated in a cap or plug 4 having a tapering socket, which cap is pierced by a suitable passage 31 communicating with the oil supply passage 32 formed in the casting 22, the latter of which is adapted to be supported by the usual bracket, not shown, through which the supply from the oil reservoir passes.

The passage 32 is controlled by a suitable valve 25 having screw-threaded engagement with a boss 33 in which it is seated, and provided with a lever 34-, from each arm of which extends a suitable chain or cord 35 for operating the said valve to open or close the passage 32, so that communication may be opened or closed between the passages 24 and 82 in said casting 22 leading to a suitable source of oil supply under pressure, not shown. To provide for ready cleaning of these passages, I prefer to arrange them as shown, the outer end of the passage 24 being closed'bya screw-plug 36,

which can be removed at will "and the passage cleanedin the usual manner.

Within the vapor generator 3 T mount an anti-pulsator consisting of a rod 11 sur rounded, at its upper end,by two or more layers of asbestos cord 10, the lower end of the rod being surrounded by a single layer 12 of such cord, and terminating in an asbestos plug 14 closing the end of a cylindrical screen 15 of wire netting, constituting a filter at the discharge end of the generator.

The oil passing downwardly under pressure through the generator flows through the annular space between the antipulsator and the walls of the tube forming the gen erator and into the larger annular space surrounded by the lower end of the vapor generator tube inclosed by the perforated cylinder 2. In this space the heat from the flames is concentrated upon the generator tube 3, thus vaporizing the oil, the supply of vapor for the heater being drawn from thetglobular chamber or reservoir 1 after the burner is put into operation by the preheating torch or alcohol cup 8, containing saturated asbestos fiber, covered by a wire gauze 9. The flame from this alcohol cup is sufficient to heat the generator in order to start the vaporization and, as soon as the vapor has passed through the orifice 80 into the vapor conduits 7 and 16, thence into the chamber 1, some of the mixture passes in fine jets through the holes 13 of the cylinder 2, and is therein ignited, when the operation of vaporization will be continuously carried on.

Extending from the sides of the globular chamber 1 are arms 26 comprising tubes or pipes of any suitable form or shape and length, each terminating, at its outer end, in a tip 27 upon which is suspended or supported a mantle 28 of any suitable form.

The upper end of the vapor generator is preferably surrounded by a cylindrical casing 17 closed by caps 20 and 21 and provided with air holes 19, through which the heated air or products of combustion passing upwardly may escape into the atmosphere. Tie rods 37 connect the two caps 20 and 21, said rods having screw-threaded engagement with the cap 21 and passing through holes in the cap 20, to which they are clamped by nuts 38 on the screw-threaded ends of said rods. This construction, not only serves to bind the parts together, but likewise permits adjustment of the air inlets 18 with respect to the discharge end of the generator, since, by manipulating the nuts 38 on the tie rods 37 the plate 20, the

casing 17, the burner tube 2, and the parts supported upon the latter can be raised or lowered and the vertical relation of the casting 6 in respect to the generator nozzle 30 can thereby be varied as desired, such adjustment contributing to the more eflicient operation of the device.

With the foregoing construction, it will be observed that the arrangement of parts lends itself to a variety of forms of fixtures, so that the same may be ornamented as desired, and any number of arms may be grouped around the central chamber 1, forming a cluster of lights disposed as may be desired, and the operating parts of the burner are inclosed in such manner that they are hidden from view and, at the same time, are so positioned as to effect the highest degree of economy in operation. The disposition of the heater, the air-mixing chamber, and the reservoir or chamber 1 is such that. when the gas mixed with air is discharged into the central chamber 1, it is fixed gas. This results in the production of a burner of maximum efiiciency and in which kerosene may be utilized with freedom from odor and without deposit of any residue.
